Letters Patent No. 108,240, dated October 1l, 1870.

The Schedule referred tc in theserLetters Patent and making part o. thesame I, WILLIAM C. Davis, of Cincinnati, Hamilton county, Ohio, haveinvented' a new and useful Improvement in (look-Stoves, of which thefollowing is a specification.

Nature mul Objects of the I nrenton.

The use of bituminous coal as fuel in cook-stoves having suggested thenecessity of sonic means ol' 'ready discharge ofthe cindcrs and ashes,various forms of shaking and dumping-gratos have been proposed, but noneof them, so far as known, fully accomplishing the .object of prompt andcomplete discharge of the contents. 1t is also found to be necessary topresent a form of grate that shall oppose no obstruction to thestirring-action of an ordinary hook or poker, and one ,that shallafford, by its height of open grating below the breast-plate, an ampleincandescent surface for the purposes of toasting, roasting, &c.

My invention relates to a construction of forwnrddumping grate,combiningI the above-recited advantages wth those of complete closure ofthe lire-front, when necessary, thelatter object being accomplished bythe pl'ovision of a suitable protuberanc, or bouncted projection, fromthe front plate| ot' the stove,

such as to enable the forward dumping ot' the grate, and the completeshutting in of the same, so as to prevent the escape ofdustand ashesinto the room.

General Description wilh reference to thc Drawing.

Figure 'l is a perspective view of a eookinglstove embodying myimprovements, the warm shelf being attached and the fire-door beingopen.

Figure 2 is a longitudinal section of the front part ofsaid stove.

Figure 3 shows the ash-pan and lifter, detached.

Figure 4 is a transverse section of the warmingshelf, together withcontiguous portions of the top and side' plates.

A represents the front plate;

B, the jambs or side plates; and

C, the top plate of my cook-stove.

'lhe mouth or opening-of the front plate is inclosed, around its top andsides, by a bonnet or projection, D, whose front .edge slopes obliquelyforward and -downward,'and is provided with a door, E, by which, inconjunction with the hearth-plate F, (which closes the ash-pit and thelower margin of the bounet,) the entire lire-chamber and ash-pit may beinclosed or shut in whenever itis desired to empt-ythe grate or toarrest the ingress of draught air to the stove.

The form and dimensions of the bonnet and heartilplate and bonnet `areclearly represented iu figs. 1 and 2, and are such as, in addition tothe objeetsjust recited, to enable the forward dumping of a highliregrate, G, such as is here shown in its normal position in tig. l,and in its discharging or dumping position.in iig. 2.

The grate is suspended by trunnions H, occupying bearings I in thestove-jambe, and one or both terminating in a square or other suitablehead, h, to take the corresponding eye j of a wrench, J, which, having al|ook,j, at its other extremity, may serve also as an ordinary lifter.The trmmions H are so located on the grate as te enable the latter toremain securely in its normal position, save when forcibly removedtherefrom by the action of the wrench; and said trunnions may be solocated as to either cause the said grate to retain its dumped positionunt-il purposely restored to its normal position, or to automaticallyreturn to said position by its own weight.

The said grate is preferably composed of a congeries of Uforme`d bars,in planes parallel to the stovejmnbs,-'nnd having no horizontal bar orparting other than the two terminal bars y g', so as to afford noobstruction to the descending ashes, or to the actionof a poker orstirrer, and also to afford the greatest possible radiating incandescentsurface for toasting or roasting.

I aux aware that gratos of cook-stovcs have been made to dump rearwardlyagainst the oven-plate or fire-back, but such devices are imperfect andobjectionable, owing to the limited passage permitted or attainable forthe descending debris.

I am also aware that gratos of cook-stoves have been adapted to dumpforward, but such gratos have been objectionable or practically useless,owing to their very limited height, and other defects of construction.

K represents a rack or perloratedjhelf, adapted to be aflixed to thestove-top, as represented, so as to form a continuation of said top,onto which shelf pots or other vessels may bc shifted froln thestove-top, when desired to be kept warm, without further cooking.

In older to utilize the ascending air which has been .heated by contactwith the stove sides, I make my said shelll in the represented open orperforated forni; and that it may be easily attached to or detached fromthe stove, there project from the under, side ot' the shelf two or morebrackets, L, which, engaging under the down-turned flange of the topplate, in the manner shown, bears against the jamh.

A series of screw-bolts, M, depending through holes in the top plate,outside of the jambs, and extending through said bracketsfare providedwith nuts N which serve to hold the shelf in place.

The said shelf is preferably perforated, andtiush with thc stove-top,.for the objects stated.

For the purpose of convenient handling without soiling of the fingers,the ash-pan U has cast on, anu combination with the bonneted projectionD and door v projecting from its inner side or sides, one or more E, andhearth-plate. F, substantially as and for tho ears, 1, which enable thepan to be lifted by means objects set forth.
